Hi,

this program BCALV_EDIT_05 should help you

and refer this

For these kind of Scenarious What you need to do is:

1. Create a Field CHECKBOX in your internal table

2. Set this field as checkbox field in the layout by using lay-box_fnname = 'checkbox'

3.If you read the Internal table in the User command it will definetly update it. But check that you may be set the property of this field as checkbox in the fieldcatalog also. If you do that it won't work.

4. That too in the grid display it won't display the check box why because it shows one button for each row. if you want to select multiple rows then you need to select them using the Ctrl+ Mouse click on the button.

5. Definetly you will solve your problem with this inforamtion

Nandha
